Abstract
Description
- This invention relates to a putting practice aid.
- A number of putting practice aids have been proposed for golfers over the years. Such aids have generally not been particularly realistic in mimicking a true golf hole. Furthermore, in many instances they have not provided an indication as to whether a golf shot has been hit at a required strength to enter a hole, i.e. if a ball is hit too strongly it will pass over the hole, or run around the edge and not enter the hole.
- An important feature with putting is that a golfer should not move their head whilst playing the shot nor immediately after playing it, and should look downwardly at the ball whilst playing the shot. With many putting aids there is a temptation for a player to raise their head whilst, or at least immediately after playing a shot, to see whether the shot is successful. This feature makes it difficult to improve one's putting significantly using such aids, and it is also difficult to obtain much feedback concerning shots played.
- According to the present invention there is provided a putting practice aid, the aid including an arrangement for producing an image of a golf hole on the ground, and a detecting arrangement for determining the speed and direction of a golf ball directed at the visual image to ascertain whether the golf ball would have fallen into a golf hole at the image.
- The detecting arrangement includes means for detecting where a ball crosses the image, and whether this would cause the ball to fall in a hole at the image. The aid may include a frame extendible spaced above the ground. The image producing arrangement may be provided on the frame and may include a light shinable downwardly to produce an image of a golf hole of a required size and shape. The image producing arrangement may include an LED which shines onto a lens.
- The detecting arrangement may include the means for producing a plurality of beams which extend across the golf hole image, and means for determining when and for how long the beams are broken by a golf ball.
- The beams may be infra red or visible light.
- The detecting arrangement may produce a pair of detection beams which are inclined relative to each other and which pass through the golf hole image and permit the speed, position and direction of a golf ball passing through the image to be determined.
- The detecting arrangement may produce an outer beam or beams to determine the general direction in which a golf ball is travelling.
- The detecting arrangement may produce a beam to determine whether a golf ball remains on or adjacent the golf hole image after a shot has been played.
- The detecting arrangement is configured such that the beams extend above the ground at a height substantially equal to the centre of a golf ball.
- The frame may include two ground engaging parts each locatable on an opposite side of the golf hole image. The detecting arrangement may include beam transmitters provided on a one of the ground engaging parts, with respective beam receivers provided on the other of the ground engaging parts.
- The aid is arranged such that after a golf shot has been played at the golf hole image, and the speed, location and direction of the golf ball has been determined by the detecting arrangement, a signal is provided to indicate whether the golf ball would have fallen into the hole.
- The signal may also indicate where the ball crossed the hole and whether this would have caused the ball to fall in the hole.
- The signal is audible, and is desirably a spoken message.

FIG. 1 is a diagrammatic side view of a putting practice aid according to the invention; -
FIG. 2 is a plan view of the aid ofFIG. 1 ; -
FIG. 3 is a cross sectional side view along the line X-X ofFIG. 2 ; -
FIG. 4 is a schematic view illustrating part of the operation of the aid ofFIG. 1 ; and -
FIGS. 5 and 6 are schematic plan views illustrating operation of the aid ofFIG. 1 . -
FIGS. 1-3 show aputting practice aid 10 locatable on theground 12 as illustrated inFIG. 1 . Theaid 10 includes two spacedground engaging feet 14 which are generally rectangular in plan view. Thefeet 14 are shown diagrammatically inFIGS. 5 and 6 . A generallysemi-circular frame 16 extends in a vertical plane between thefeet 14 and mounts a downwardly directedlight unit 18 at its mid-point. Aretractable handle 20 is provided above thelight unit 18 to permit carrying of theaid 10. - The
light unit 18 includes a downwardly directingLED light source 22. Atube 24 is provided beneath thelight source 22 and aconvex lens 26 is provided at the lower end of thetube 24.FIG. 4 illustrates how the light from thesource 22 is directed by thelens 26 to provide acircle 28 of light on the ground of the same size as a standard golf hole, i.e. with a diameter of around 108 mm. - Five
beam transmitters 30 are provided in theleft hand foot 14 as shown inFIGS. 1 and 3 . Thetransmitters 30 produce infra red beams, modulated at 38 kHz (nominal). Correspondingbeam receivers 32 are provided in theright foot 14 as shown inFIGS. 1 and 3 . Thetransmitters 30 produce fivebeams 34 as shown inFIG. 5 and described in further detail below. Theaid 10 also comprises a control unit and loud speaker. - In use the
aid 10 is located where required which may be indoors or outdoors, and the unit is particularly suited to indoor practice. Thelight source 22 is illuminated to produce thecircle 28 on the ground beneath theaid 10. A golf ball can then be struck from any direction aiming to pass as near as possible beneath the centre of thecircle 28. As the ball passes through or near thecircle 28 therespective beams 34 are broken. The timing and duration of the break of therespective beams 34 is measured to determine the outcome of the shot as if thecircle 28 had been a real golf hole. - The determination of this outcome will now be described. The
transmitters 30 produce front and rearouter beams beams beam 40 is first broken it will be determined as a forward shot, whilst if thebeam 42 is first broken this will be considered a backward shot. Once the other of thebeams - Two
detection beams outer beams detection beams right hand foot 14 as shown in the drawings, but thedetection beams beam 40 to initiate the measurement sequence, thedetection beam 44 nearest thebeam 44 will then be broken. The duration of the breaking of thebeam 44 is measured in msec, and when this is divided into the ball diameter, conventionally 43 mm, this provides a velocity in mm/msec. - The time between breaking of the
detection beam 44 and thedetection beam 46 is also measured. This is then multiplied by the velocity to provide the distance travelled in the direction of the ball movement. The direction of movement is shown by theline 48, and the distance travelled between thebeams line 50. The gap is then divided by the tangent of the angle α to provide the lateral position of the gap along the beam system, from theright foot 14. This lateral position is shown by theline 52. - The ball then proceeds through the rear
outer beam 42 to complete the sequence. All of thebeams - Once the lateral position of the line of the ball has been established, the result of the putt is calculated by comparison with preset values corresponding to five zones within the hole as shown by the
circle 28, and two zones outside the hole. These zones are illustrated inFIG. 6 and from left to right are respectively: missed left 54;left lip 56; left ofcentre 58; centre of hole 60; right ofcentre 62;right lip 64; and missed right 66. If the ball passes through one of the five zones within the hole, and the velocity is not greater than 1.14 mm/msec, the ball is considered as entering the hole. - Once the position and speed of the ball has been determined, an audible message will be given through the loud speaker to indicate whether the shot has been successful or is a miss and where in or outside of the hole the ball passed. A
central beam 68 is also provided which is only considered if the measurement sequence fails to complete because both of theouter beams beam 68 if activated will detect if a ball remains in or adjacent thecircle 28, and an appropriate audible signal will be provided to suggest that the ball should now be removed from this location. - There is thus described a putting practice aid which by virtue of a virtual golf hole provides a realistic target. The aid also provides a signal as to whether the ball would have landed in the hole, and where it would have entered the hole. This provides verbal feedback to the player, relating to the line and speed of each putt, to allow them to modify their action or technique as required.
- As an audible signal is provided there is no requirement for a player to raise their head to see where the putt has gone. An indication of whether or not the ball was over hit and therefore would not have landed in the hole is provided, and again without the requirement for a player to look up to see where a ball has finally come to rest.
- The aid is of relatively simple construction and can thus be robustly manufactured for long term reliable use. No calculations are required by a user, but an accurate indication of the outcome of shots is readily and rapidly provided.
- Various modifications may be made without departing from the scope of the arrangement. For instance, a different arrangement of beams may be used, and the beams could be other than infra red, and could be light beams. A different light unit could be provided. A different arrangement of zones could be used.
- Accordingly, while the invention has been described with reference to the structures and processes disclosed, it is not confined to the details set forth, but is intended to cover such modifications or changes as may fall within the scope of the following claims.
